Hogyan tudnék egy egyedi 64HEX privátkulcsból álló .txt fájlt átkonvertálni Ethereum címre?

for line in infile:

IndentationError: expected an indented block

Így írtam be:

import sys

from ecdsa import SigningKey, SECP256k1

import sha3

addresses = []

with open('HEXminta.txt', 'r') as infile:

for line in infile:

hex_priv_key = line.strip()

keccak = sha3.keccak_256()

priv = SigningKey.from_string(string=bytes.fromhex(hex_priv_key),

curve=SECP256k1)

pub = priv.get_verifying_key().to_string()

keccak.update(pub)

address = keccak.hexdigest()[24:]

addresses.append('0x'+ address)

with open('addresses.txt', 'w') as outfile:

for address in addresses:

outfile.write(address + '\n')
